Equilibrium
A body's ability to resist a change in its current state.
What is stability?
The path that projectiles in motion follow.
What is a parabolar?
The three categories of fundamental motor skills.
What are locomotor, manipulative, and stability?
An object will stay at rest or travel in the same direction at a constant velocity unless acted on by an unbalanced force.
What is Newton's First Law?
The force that keeps us on the ground at an acceleration of 9.8 m/s squared.
What is gravity?
A theoretical line that passes through the centre of gravity.
What is line of gravity?
The two components of projectile motion.
What is vertical and horizontal?
Shooting an arrow in archery requires a combination of these.
What are gross and fine motor skills?
Newton's Second Law.
What is a body's acceleration is proportional to the force applied to it and the direction in which the force is applied. Force = mass X acceleration.
A body's resistance to change its rotation rate.
What is moment of inertia?
Centre of gravity.
What is the central point around which a body's weight is balanced?
The factors affecting a projectile's path.
What are angle of release, speed of release, and height of release?
Discrete motor skills.
What are motor skills with a specified beginning and end? For example, serving in tennis or swinging a golf club.
A basketball being shot in the air before falling through the net.
What is Newton's First Law?
The sequential and coordinated movement of body parts to create maximum velocity.
What is summation of momentum?
A method of increasing stability.
What is increasing the base of support size, ensuring the line of gravity falls within the base of support, lowering the centre of gravity, increasing mass, increasing friction, extending the base of support in the direction of the oncoming force, or shifting the line of gravity towards the oncoming force?
The optimal angle of release to maximise vertical height.
What is greater than 45 degrees?
Externally paced; low predictability; high variability.
What are open motor skills?
When a person performs a high jump, they exert a force that causes them to move away from the earth and the earth to move away from the.
What is Newton's Third Law?
The speed at which an object rotates around an axis.
What is angular velocity?
When an object is moving with a constant velocity with no change in its speed or direction.
What is dynamic equilibrium?
Increasing speed and height of release with the angle of release slightly below 45 degrees.
What is the method of maximising horizontal distance?
Influences on movement such as rules, equipment, and required speed and accuracy.
What are task-related constraints?
When a swimmer pushes off a wall to return to the other end at a rate proportional to the force they applied to the wall.
What is Newton's Second Law?
The product of moment of inertia and angular velocity: an object's tendency to keep spinning.
What is angular momentum?
